IIOSE-NOZZLE-THREAD ADAPTER.

Application filed November '7, 1916.

To all whom it may concern:

Be it known that 1, CHARLES R. GREEN, a citizen of the United States,and a resident of Florence, county of Burlington, State of New Jersey.have invented certain Improvements in Hose-l lozzle-Thread Adapters, ofwh ch the following is a specification.

The object of my invention is to improve the construction of hose nozzlethread adapters for coupling fire hose to the nozzles of fire hydrants,so that the adapter can be readily applied to the nozzle.

The invention is an improvement upon that set forth and claimed in anapplication for patent filed by Newton Morton of even date herewith, andrelates particularly to the details of construction of the mechanism foractuating the jaws.

In the accompanying drawing Figure 1, is a side view of my improvedadapter;

Fig. 2, is a longitudinal sectional view showing it connected to thenozzle of a hydrant;

Fig. 3, is a plan view; and

Fig. t, is an end view.

Referring to the drawing, 10 is the body portion having a threadedsection 11 adapted to receive the coupling of the hose to' which it isattached. At the opposite end of the body portion is a washer 12 whichabuts against the end of the nozzle 18. in the present instance of afire hydrant.

@n the body portion are three lugs 14, forked at their outer ends toreceive the sliding jaws 15. The jaws are held in position by pins 16which pass through elongated openings 17 in the jaws, so that the jawswill have a certain amount of freedom.

The forward end of each jaw is enlarged and is provided with teeth 18,which engage the threads on the nozzle 13, and the rear end 19 of eachjaw is turned at an angle in respect to the main portion of the aw andSpecification of Letters Patent.

asct screw 20 is adapted to a threaded opencontact with the threadedportions of the nozzle. clamping'it sul'liciently so that, when theadapter is turned, the jaws act as a nut, causing the packing in the endof the adapter to come in close contact with the end of the nozzle,making a water tight joint. After the adapter has been coupled to thenozzle of a hydrant, the hose coupling can be easily coupled to theadapter by screwing it upon the section 11 of the body portion of theadapter.

While I have shown my improved adapter as having three sliding jaws, insome instances two jaws may be used, or more than three, withoutdeparting from the essential features of the invention.

The combination in a hose nozzle thread adapter. of a hollow bodyportion having means at one end adapted to receive the coupling of ahose, and having at the opposite end a pack ng ring; lugs on the bodyportion having forked extremities and beveled rear sides; sliding jawsmounted in the forks of the lugs by means of pivot pins, each jaw havinga slot therein through which the pivot pin extends and being adapted toengage at one end the thread on the hydrant nozzle and having a rightangled portion at the opposite end: and a set screw mounted in the rightangled portion and bearing against the beveled lugs so that, on turningthe set screws, the jaws can be clamped to the nozzle and the packing onthe end of the body portion will b: forced against the end of thenozzle, making a tight joint.
